OIL-CAN SPOUT.

SPECIFICATION forming part of Letters Patent No. 237,817, dated February15, 1881.

Application filed June 24, 1880.

To all whom it may concern:

Be it known that I, TIMOTHY O. CHALK, of Valley Falls, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in Oil-Gan Spouts; and I hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming part of this specification.

The object of this invention is to facilitate the flow of oil from thespout of an oil-can by admitting a small quantity of air to the interiorof the oil-can.

My invention consists in an oil-can embodying certain features ofconstruction, as will hereinafter be described, and pointed out in theclaim.

Figure l is a View of an oilspout, shown partly in section, the oil-canbeing shown in broken lines, and shows the spout provided with anair-inlet above the can and a U-shaped tube connecting with theair-inlet, the air-outlet being close to the tube in the spout. Figs. 2and 3 show modifications for connecting the U-shaped tube with theairinlet, the air-exit being near the entrance to the spout. Fig. 4 is asectional view of part of a spout provided with an air-inlet tube theend of which connects with a hollow sphere in which a small air-outletis provided.

In the drawings, a represents the spout of an oil-can; I), the airinlet,located above the screw-threaded portion of the spout; and c, the tube,communicating at one end with the air-inlet b, and extending below thelower end of the spout,'and then formed into a returnbend, theair-outlet at being located in close proximity to the oil-inlet of thespout. The

bent tube 0 is bent so as to occupy less space than the diameter of thespout, and thus be adapted for ready insertion in the oil-can. As thecan is tipped up for discharging oil air flows into the can, it beingdischarged in line with the flow of the oil, and as the oil forms acurrent from the open end of tube 0 the oil has a tendency to draw theair into the can, and, further, the tubeis prevented from filling withoil, this latter result being effected owing to the current of oilflowing in the same direction as the discharge of air from the tube 0.

e is a bulb or hollow sphere, secured to the tube 0. It is provided withthe air-outlet d, as shown in Fig. 4. By the use of the bulb c or theU-shaped tube 0 the air-outlet is protected against the entrance of oil,and by placing the air-tube into the spout the whole can be readilyremoved by removing the spout.

The peculiar construction insures durability, economy in construction,and efliciency.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent The combination, with an oil-can, of an oilcan spouthaving an air-inlet located above its screw-threaded portion and anair-tube coinmunicating at one end with said air-inlet, the opposite endof the tube being formed into a return-bend occupying less space thanthe di- 'aiueter of the spout, the extreme end of the tube being locatedin close proximity to the inlet of the spout, substantially as setforth.
